- /**
- * nsIDragSessionOS2 encapsulates support for OS/2 dragover/drop events,
- * i.e. operations where Mozilla is the target of a drag (nsIDragService
- * handles source operations). Its public methods correspond to the d&d
- * messages a PM window receives. Its protected methods recast native
- * data as nsITransferable flavors during drag-enter and drop events.
- *
- * nsIDragSessionOS2 supports these native formats: WPS Url objects,
- * files, the contents of files (Alt-drop), and text from DragText.
- * Data is presented to Mozilla as URI-text, HTML, and/or plain-text.
- * Only single-item native drops are supported. If the dropped file
- * or text does not exist yet, nsIDragSessionOS2 will have the source
- * render the data asynchronously.
